DYU D1 does not work anymore

[Arnaud 0]

Dear,

My son used his DYU for 1 year now and sudently nothing worked.

I plug the charger, it's coming green when the battery is full but the trottle does not light, on/OFF button does not work, etc.

Where is trouble coming from?

I do not have complete explanation from my son what's happen exactly.

Do I change the controller card or motor? where can I buy them?

Regards

Hello, could you please tell me whether the indicator light of the charger is red when the car starts to charge, and it turns green after a few hours? 
Or if when the ebike is charged, turn on the ebike and check out the horn is ringing or not. Let me know so we can find out where is trouble coming from, thanks.
